Live › vulnerability › CVE-2026-119672
mongofiles, a MongoDB Database Tools command, uses a filename stored in the database as the output path when retrieving a file without --local. A user who can edit GridFS file metadata can set the name to '-', so a later retrieval by a privileged operator writes the file contents to standard output, where a user with access to that output may read them.
Summary written from the sources below. Check the originals before acting.

Teams that run MongoDB Database Tools from version 3.1.4 up to, but not including, 100.20.1 and use mongofiles to retrieve GridFS files without an explicit --local destination. Exposure also requires a user who can change GridFS file metadata and a way to read the captured standard output. Teams that do not use mongofiles, or always pass --local, are not affected by this path.

MongoDB Database Tools mongofiles uses a database-stored GridFS filename as the output destination for get_id when --local is not specified. A user who can modify the file metadata can set the stored filename to '-', causing a later authorized retrieval to write the file contents to standard output instead of a local file. If standard output is captured in a location accessible to that user, this may disclose GridFS content the user cannot read directly. Exploitation requires a higher-privileged operator to retrieve the affected file without an explicit local destination and attacker access to the captured output. This issue affects MongoDB Database Tools from version 3.1.4 through versions before 100.20.1.
